Noise in Circuit Quantum Electrodynamics — •Michael Marthaler1, Gerd Schön1, and Alexander Shnirman2 — 1Institut für Theoretische Festkörperphysik and DFG-Center for Functional Nanostructures (CFN), Universität Karlsruhe, 76128 Karlsruhe, Germany — 2Institut für Theorie der Kondensierten Materie, Universität Karlsruhe, 76128 Karlsruhe, Germany
Qubits and superconducting single electron transistors (SSET) have been used to reproduce effects known from quantum optics in solid state based systems. In this type of system we have to consider noise sources which are different from known dissipation effects in quantum optics. We investigate the effect of the electromagnetic environment in circuit quantum electrodynamics (CQED) for a stripline pumped by a superconducting single electron transistor (SSET).
